I have recently returned to NWN2, and I can say that Realms of Trinity is as great as ever. In a time when some servers are dying off, RoT is still going strong with many active players. It is a great server for any play style. There is a ton of content, including quite a bit of truly epic (and still challenging) content. It is a great place to play for power gamers and role-players alike. There is even a system to substantially reward good roleplaying.
All in all, I think RoT is the best NWN2 has to offer! Look for me in game. Everyone is very helpful (and sometimes generous) with new players!
